RailGiants Train Museum Sep. 2026

RailGiants Train Museum at the Los Angeles County Fairgrounds in Pomona, California is a historical journey back to the glory days of the American Railroad. Our Museum houses some of the country’s most well-preserved locomotives, which includes several sole survivors of their respective classes. Our RailGiants collection contains two of the four surviving 3-Cylinder steam locomotives; SP #5021 and UP #9000. The largest diesel locomotive, a Union Pacific “Centennial,” is also here. In addition to our locomotives, we have various pieces of Rolling Stock (freight and passenger cars) , our historic Arcadia Depot, library archives, and gift shop. We are open free to the public during the second weekend of each month, except in May, from 10 am to 5 pm. Ample parking is available.
